I upgraded 2 days ago from Ubuntu 20.04 to Ubuntu 22.04. After that when I open Software & Updates, either from GUI or cli (using update-manager command) it runs fine and at the end it says: The software on this computer is up to date. I have then the option for "Settings and Livepatch...". When I click on it nothing appears, but in the terminal I receive the following error message.

Traceback (most recent call last):   
File "/usr/bin/software-properties-gtk", line 100, in <module> app = SoftwarePropertiesGtk(datadir=options.data_dir, options=options, file=file)

gi.repository.GLib.GError:

The file is present and file type seems correct.

$ ls -l /usr/share/software-properties/ubuntu-pro-logo.svg

Do you have any suggestion about what to check?

Is it possible there's a package missing. Try `sudo apt install ubuntu-desktop^` (the caret is important) - which will put back anything that went astray in the upgrade.

Run the command, but no positive effect, same error. Furthermore libreoffice was reinstalled, but it's a minor issue. Any further suggestion?

Sorry, no. I clean installed Ubuntu 20.04 and upgraded to 22.04. It all works fine. I wonder if there's a mime problem. Can you try `sudo update-mime-database /usr/share/mime` and `sudo /usr/lib/x86_64-linux-gnu/gdk-pixbuf/gdk-pixbuf-query-loaders --update-cache`. Then try again?

I found no /usr/lib/x86_64-linux-gnu/gdk-pixbuf directory. How can I check and install it?

Apologies, I got the folder name wrong. it's `sudo /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders --update-cache`

Excellent! I've turned my comment into an answer, you can mark that as useful.

When this happens, you can often resolve it by regenerating mime caches with these two commands:

sudo update-mime-database /usr/share/mime and

sudo /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders --update-cache

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
